Phil Mui, currently the group product manager for Google Analytics, will be joining marketing services and technology company Acxiom as chief product and engineering officer.

According to Acxiom, Mui will report to CEO Scott Howe, lead a team of more than 750 people, and play “a decisive role” in the company’s plans to increase research and development. In the the hiring press release, Howe calls Mui “the capstone of our strategic initiatives.” Earlier this year, Warren Jenson joined as the company’s chief financial officer (he was formerly CFO at Electronic Arts and Amazon.com), and Nada Stirratt joined as the first chief revenue officer (a role she served at MySpace).

Mui forwarded me the following statement, which he’s sending to the Google Analytics team:

I love Google Analytics, our people, our partners and our users all these past 6+ years. Since joining Google in 2005, I have grown as a person, as a leader, and have made many friends in Google and in the Analytics industry. It has not been a job; Analytics is what I do and am.

Acxiom turns out to be the twin brother which Google Analytics has always wanted to have, in order to complete the 360 degree view of customers. I am taking the unthinkable step next month away from GA to lead this team in Foster City, CA, starting sometime in May.”
